Stage 20 of the 2026 Vuelta a España starts at 11:36 BST on Saturday 12 September, with UK television coverage beginning at 11:00 BST on TNT Sports 3. The full stage is also available to stream on HBO Max.
This is the last major mountain stage of the race and the final realistic opportunity to change the red jersey before Sunday’s finish in Granada. Enric Mas starts with 1:37 over Primož Roglič, after neither Roglič nor Felix Gall could distance him on Friday’s long ascent of Peñas Blancas. Gall remains third at 3:01, Richard Carapaz is fourth at 5:17 and Oscar Onley fifth at 6:03.
The 186.8km route from La Calahorra to Collado del Alguacil contains almost 4,900 metres of climbing, with most of the serious difficulty packed into the second half. The decisive viewing window should begin from around 14:20 BST, when the riders are expected to start their second ascent of Puerto de El Purche. Puerto de El Duque follows before the final 8.3km climb to Collado del Alguacil, which should begin at roughly 16:05 BST.

What time does Vuelta a España Stage 20 start?
The riders roll away from La Calahorra for the neutralised start at 11:30 BST, with the official racing start scheduled six minutes later at 11:36 BST.
TNT Sports begins its UK coverage at 11:00 BST, so viewers can join before the flag drops rather than coming into the race after the breakaway has formed.
The official schedule is:
- TNT Sports 3 and HBO Max coverage: 11:00 BST
- Neutralised start: 11:30 BST
- Racing start: 11:36 BST
- Expected finish: approximately 16:30 BST
- Official finish window: roughly 16:16-16:47 BST
The finish time depends heavily on how aggressively the stage is raced. There is an unusually demanding sequence of climbs from the first ascent of El Purche onwards, and an early GC battle could push the speed above the organiser’s central estimate.
How to watch Vuelta a España Stage 20 in the UK
TNT Sports 3 has live television coverage of Stage 20 from 11:00 BST.
The same coverage is available to stream through HBO Max, which replaced Discovery+ as the main streaming home for TNT Sports cycling in the UK. Every stage of this year’s Vuelta is available through the service.
Our full guide to watching the Vuelta a España 2026 in the UK covers the wider television and streaming arrangements for the race.
The early broadcast is useful on Saturday because the stage is not designed around a short final burst of climbing. There is enough difficult terrain before Collado del Alguacil for Red Bull-Bora-Hansgrohe, Decathlon CMA CGM or EF Education-EasyPost to begin changing the race long before the final ascent.
Vuelta Stage 20 key times for UK viewers
These timings use the organiser’s central 38km/h schedule and should be treated as estimates once the race is underway.
| Point on Stage 20 | Approximate UK time |
|---|---|
| TNT Sports 3 / HBO Max coverage starts | 11:00 BST |
| Neutralised start | 11:30 BST |
| Racing start | 11:36 BST |
| Puerto de Los Blancares summit | 12:46 BST |
| First Puerto de El Purche begins | 13:29 BST |
| First Puerto de El Purche summit | 13:53 BST |
| Second Puerto de El Purche begins | 14:20 BST |
| Second Puerto de El Purche summit | 14:44 BST |
| Puerto de El Duque summit | 15:35 BST |
| Collado del Alguacil begins | 16:05 BST |
| Expected finish | 16:30 BST |
The final two hours are the safest target if you cannot watch from the start. By around 14:20 BST the peloton should be beginning El Purche for the second time, with nearly all of the stage’s meaningful GC terrain still ahead.
What time should you start watching Stage 20?
Start watching by 14:15 BST if you want to see the complete GC battle develop.
That puts viewers in place before the second ascent of Puerto de El Purche, 8.2km at 8.1%. The climb is difficult enough on its own, but its importance comes from being tackled twice and followed by another first-category ascent before the finish.
The second El Purche summit is expected at around 14:44 BST. From there, the stage heads towards Puerto de El Duque, a 7.4km climb at 8.3% whose summit comes with 31.4km remaining.
If Roglič intends to do more than attack Mas in the final few kilometres, this is the part of the stage where his options begin to narrow.
Waiting for Collado del Alguacil would leave him with only 8.3km to recover 1:37 from a rider who has repeatedly matched or beaten him in the mountains during this Vuelta. An earlier move carries more risk but gives him substantially more road on which to turn an attack into a race-changing gap.
Our state of the Vuelta analysis before the final week identified Collado del Alguacil as the last stage capable of completely overturning the race. The gap has changed since then, but the basic point has become even stronger. There is now no meaningful GC terrain left after Saturday.

Friday offered Roglič his first opportunity to take back some of the time he lost to Mas in the mountains, but Peñas Blancas ended without any change among the leading five riders.
Eddie Dunbar won the stage from the breakaway after catching and passing Santiago Buitrago inside the final 400 metres. Behind them, Red Bull-Bora-Hansgrohe increased the pace before and during the final climb, while Roglič attacked inside the final two kilometres.
Mas responded.
Gall and Carapaz also tried to create movement, but Mas, Roglič, Gall, Carapaz and Onley eventually finished together, leaving the important GC gaps unchanged.
That result was particularly useful for Mas. Roglič had already failed to take as much time as he needed in Thursday’s Jerez time trial, where he gained only 33 seconds despite having the course most obviously suited to him.
Our Stage 18 report explains how Mas turned what had looked like the most vulnerable day of his race into one of the performances that strengthened his grip on red.
The Stage 19 preview then posed the next question: could Roglič actually distance Mas once the Vuelta returned to the mountains?
Peñas Blancas provided the answer for another day. He could not.
Saturday is the last chance to change it.
Puerto de El Duque should be the point where the GC race becomes serious
Puerto de El Duque reaches its summit at approximately 15:35 BST on the central schedule.
That leaves 31.4km to race.
The climb itself is 7.4km at 8.3%, coming after both passages of El Purche. Riders who have spent too much energy earlier in the stage will already be exposed, while teams that still have several mountain domestiques available will have a major tactical advantage.
For Roglič, El Duque offers something Collado del Alguacil does not: distance.
An attack there leaves enough road to establish a gap, potentially link up with a teammate from an earlier breakaway and force Movistar to chase.
It also comes with an obvious cost. There is a descent and flatter section before the final climb, meaning a rider who attacks alone could use considerable energy defending only a small advantage.
Gall and Carapaz complicate that calculation. Gall is only 1:24 behind Roglič in the fight for second overall, while Carapaz still has a route towards the podium. Neither has much reason to spend the stage helping Mas keep everything together.
That is why this could become a much more open race than Friday’s final climb.
What time does the Collado del Alguacil climb start?
The riders are expected to reach the foot of Collado del Alguacil at approximately 16:05 BST.
The final climb is 8.3km at an average of 9.8%, gaining 816 metres before the finish at 1,884 metres. It is a new Vuelta summit finish and the last major climbing test of the 2026 race.
The official timings give a fairly broad window:
- Fast schedule: climb begins around 15:51 BST, finish around 16:16 BST
- Central schedule: climb begins around 16:05 BST, finish around 16:30 BST
- Slow schedule: climb begins around 16:19 BST, finish around 16:47 BST
Anyone tuning in specifically for Collado del Alguacil should therefore be watching before 15:50 BST.
Waiting until 16:05 risks arriving after the climb has already started if the race has been fast.
Mas starts the day with 1:37 to defend
The overall situation gives Stage 20 its shape.
Mas leads Roglič by 1:37. Gall is 3:01 down, Carapaz trails by 5:17, and Onley starts fifth at 6:03.
Roglič’s deficit is large enough that a familiar late acceleration is unlikely to solve the problem. Taking ten or 15 seconds near the summit does not meaningfully change who leads the Vuelta.
He needs either a much longer attack or a genuine collapse from Mas.
Nothing on Peñas Blancas suggested the latter is imminent. Mas stayed with every meaningful move despite a long, aggressive stage and another 4,000 metres of climbing in the legs.
The burden therefore sits increasingly with Roglič and Red Bull to make Saturday different.
Mas can afford to ride according to the gap. Roglič cannot.
Stage 20 is the last day to change the Vuelta
Sunday’s final stage finishes in Granada but is classified as flat. Unless something extraordinary happens, the riders who leave Collado del Alguacil first and second overall will arrive in the same order at the end of the Vuelta.
That makes Saturday the point at which all of the accumulated calculations from the previous three weeks run out.
The wider 2026 Vuelta route deliberately placed the long Jerez time trial immediately before Peñas Blancas and Collado del Alguacil. Roglič had the opportunity against the clock. Mas then survived the first mountain response.
Only one test remains.
UK viewers can watch it from 11:00 BST on TNT Sports 3 and HBO Max, with the race itself beginning at 11:36 BST. If you are joining later, aim for 14:15 BST to catch the second ascent of El Purche and everything that follows.
If the fight for red waits until Collado del Alguacil, expect the final climb from around 16:05 BST.
If Roglič is going to find the 1:37 he still needs, the more interesting possibility is that the race starts much earlier than that.
